Dutch researchers created a drone that flies like a fruit fly

A joint team of engineers and scientists from Delft University of Technology’s Micro Air Vehicle Laboratory (MAVLab) and Wageningen University & Research have created an autonomous winged drone that can mimic the flight mechanics of a fruit fly. If you have ever tried swatting a fruit fly, you know how maneuverable they are. Not only can the robot make a 90-degree turn with virtually no lost momentum, but it can also almost instantly reverse direction to execute turns tighter than 90 degrees.
